MF is not dead, you should consider the split however. The bulk of photos are snapshots. In that world digital will rule, in volume commercial photography digital is also the way to go. However for fine art photography for example, film will always have a place. As to MF, there is a certain disciplne with this format that can really help improve your skills. I always encouraged my students to get a Yashica MAT124 or Rollieflex. The fixed lens MF really changed their work for the better. Of course it is not a one size fits all, but it clearly puts the focus on the image and the message.
